AUTOMATIC WATERlNG-TROUGH.

SPECIFICATION forming part of ale tters jratent N0. 783,068, dated February 21, 1905.

Application filed May 10, 1904. Serial No. 207,228.

' have invented a new and useful Automatic VVatering-Trough, of which the following is a specification.

This invention relates generally to troughs for watering stock, and particularly to the valves thereof.

The object of the invention is to improve the construction of such valves by rendering them capable of vertical adjustment to regulate the height of the water in the trough and by disposing them in such manner that they cannot be put out of order by an animal drink ing at the trough.

WVith these objects in view the invention resides in a water-trough having a removable valve-chamber formed with an outlet in its bottom, a float-valve, and a vertically-adjustable supply-pipe cooperating with the valve.

The invention also resides in the particular combination of parts and in the precise details of construction hereinafter described with reference to the accompanying drawings, forming part of this specification, where-- Figure 1 is a perspective view of a trough constructed in accordance with the invention. Fig. 2 is a longitudinal section. Fig. 3 is a detail perspective view of the valve-chamber. Fig. A is a similar view of the float-valve.

The reference-numeral 1 indicates a watering-trough which is preferably rectangular in cross section. Removably fitted into the trough 1 is a valve-chamber formed with a top 2, which projects over the sides of the trough, end pieces 3 4, and a bottom 5, the sides being omitted to permit insertion of the floatvalve presently to be described and their place being supplied by the sides of the trough. The projecting top 2 of the valve-chamber supports it in the trough and prevents it from dropping down thereinto. When the valvechamber is in position, its sides are closed by the sides of the trough. A perforation or outlet 6 is formed in the bottom 5 of the valvechamber, which is located above the bottom of the trough in order that water may pass Located inside the valve-chamber is a fioatvalve 7, which preferably is constructed in the form of a hollow tin disk. A seat 8 is set into a depression in the upper surface of the float-valve 7. Above the seat 8 is an inlet-pipe 9, which passes through the top 2 of the valve-chamber. An annular fiange 10, fastened to the top 2 of the valve-chamber, surrounds the inlet-pipe 9, which is adjustable vertically, a set-screw 11, passing through the flange 10 and contacting with the peripl cry of the pipe 9, permitting this vertical adjustment.

At its lower end the pipe 9 is reamed out interiorly. as shown at 12, to produce a sharp edge for contacting with the seat 8 when the float-valve rises sufficiently to stop the flow of water, and thus insure a positive cutting off of the supply, and, furthermore, at all times a positive coaction between the seat and the lower end of the supply-pipe, this being secured by reason of the fact that the sharpened edge will operate to cause the contact between it and the seat to be true.

The trough 1 may be divided into sections by means of cross-pieces 18, provided with serrated strips 14 of leather or other suitable material. These cross-pieces serve to separate the animals from each other while drinking and to prevent them from lighting or crowding together or against the valve-chamber.

The manner of using the trough will be understood from the foregoing description. The float-valve is placed in the valve-chamber, which is then lowered into the trough. The inlet-pipe is fitted through the top of the valve-chamber and adjusted vertically therein to secure the desired depth of water in the trough. When the water in the trough is below the desired level, the float-valve is not in contact with the open end of the inlet-pipe, and consequently sufficient water is permitted to flow therefrom to fill the trough to the proper level.

The device of the invention is simple and inexpensive in construction. The few parts are adapted to be easily assembled and can be taken apart at any time if the valve wears out. The closed chamber effectually protects the valve against derangement by the animals When drinking at the trough, and the adjustable inlet-pipe permits the level of the Water to be, regulated and changed at any time.

Modifications in the particular arrangement of parts and details of construction illustrated and described may be made Within the scope of the following claim without departing from the spirit of the invention.

I claim- A Water-trough having therein a removable valve-chamber comprising a top resting on In testimony that I claim the foregoing as my oWn I have hereto aflixed my signature in the presence of two Witnesses.
